Is it true that fall through spring applications of Devrinol 50-DF Ornamental are preferred if irrigation is not available?

Applying Devrinol 50-DF Ornamental from fall through spring is beneficial, particularly in scenarios where irrigation isn't available. This herbicide is a pre-emergent that works best when it is activated by moisture to form a barrier that prevents weed seeds from germinating. In areas lacking irrigation, applying the herbicide in the fall allows it to establish a protective layer before winter, which is critical since this is a time when many weeds start to germinate. The continued effectiveness through spring helps maintain weed control until the growing season, when other management practices may come into play. This approach maximizes the product's utility and helps ensure effective weed control throughout the critical periods when weeds are likely to compete with ornamental plants for resources.
